Ten Years, Four for an EU Citizen, Two if a Grandparent Was Italian

Answer

The general rule applies to you

No exception is recorded for citizens of Saint Lucia on this topic. That is the answer, not a gap - everything below is the rule you get, unchanged.

98 exceptions recorded across 37 countries · none match Saint Lucia to Italy · Becoming a citizen

Italian naturalisation is granted by presidential decree and the waiting period depends on who you are. Ten years of legal residence for a foreigner with no other connection. Four for a citizen of a European Union member state. Five for a stateless person, and five for someone adopted as an adult by an Italian or who has served the State for five years. Three for someone born in Italy. Two for someone whose parent or grandparent was Italian by birth. Marriage is a separate article with its own clock: two years of legal residence in Italy after the wedding, or three years from the wedding if the couple lives abroad, each halved where there are children.

What applies to you

Nothing changes for a citizen of Saint Lucia

We have no rule recorded that treats your citizenship differently here, so the general rule above is the one that applies to you. That is an answer, not a gap.

What the law says

Text layer - verbatim verifiedLegge 5 febbraio 1992, n. 91, Nuove norme sulla cittadinanza, testo vigente · Articolo 9, comma 1
«La cittadinanza italiana puo' essere concessa con decreto del Presidente della Repubblica, sentito il Consiglio di Stato, su proposta del Ministro dell'interno: a) allo straniero del quale il padre o la madre o uno degli ascendenti in linea retta di secondo grado ((sono o)) sono stati cittadini per nascita ((e che risiede legalmente nel territorio della Repubblica da almeno due anni)) , comunque fatto salvo quanto previsto dall'articolo 4, comma 1, lettera c); a-bis) ((allo straniero nato nel territorio della Repubblica che vi risiede legalmente da almeno tre anni)) ; b) allo straniero maggiorenne adottato da cittadino italiano che risiede legalmente nel territorio della Repubblica da almeno cinque anni successivamente alla adozione; c) allo straniero che ha prestato servizio, anche all'estero, per almeno cinque anni alle dipendenze dello Stato; d) al cittadino di uno Stato membro delle Comunita' europee se risiede legalmente da almeno quattro anni nel territorio della Repubblica; e) all'apolide che risiede legalmente da almeno cinque anni nel territorio della Repubblica; f) allo straniero che risiede legalmente da almeno dieci anni nel territorio della Repubblica.»

All seven periods in one list. The ten years are the last line, not the first: the article is written as a set of shorter routes with a default at the end.

The Italian state's portal for legislation in force. It shows each article as currently amended, with an explicit testo in vigore dal date, and links the amending instruments.

Standing: Maintains the text in force

Cannot be cited for: It gives the text and not its interpretation. Article 3-bis reads clearly and has still generated years of litigation over what it means, which is why the Constitutional Court is watched alongside it. A consolidated text can also lag a very recent amendment.

«Il coniuge, straniero o apolide, di cittadino italiano puo' acquistare la cittadinanza italiana quando, dopo il matrimonio, risieda legalmente da almeno due anni nel territorio della Repubblica, oppure dopo tre anni dalla data del matrimonio se residente all'estero, qualora, al momento dell'adozione del decreto di cui all'articolo 7, comma 1, non sia intervenuto lo scioglimento, l'annullamento o la cessazione degli effetti civili del matrimonio e non sussista la separazione personale dei coniugi. 2. I termini di cui al comma 1 sono ridotti della meta' in presenza di figli nati o adottati dai coniugi.»

Marriage, with the two clocks and the halving. The Constitutional Court has been here, and the update note attached to this article in the consolidated text says so.

Practical notes

Naturalisation is a concession, not a right: the article says the citizenship may be granted by decree, on the Interior Minister's proposal and after the Council of State is heard.

A descendant's two-year route in paragraph (a) is read together with article 3-bis, which decides whether the person was a citizen already. The ancestry record carries that.
